OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 582,842, dated May 18,1897.

Application filed December 24, 1896- Serial No. 616,911. No model.)

To all whom, it may concern.-

Be it known that we, WILLIAM ADLER and WILLIAM J. LEWIs, citizens of theUnited States, residing at Philadelphia,in the county of Philadelphiaand State of Pennsylvania, have invented certain new and useful1mprovements in Oil-Stoves; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to oil-stoves, and the object in view is toprovide a stove-which will neither emit gas, smoke, nordust, which willbe odorless and cleanly, and at the same time combine simplicity,cheapness, and utility in a high degree.

Another object of the invention is to economize in the consumption offuel and to furnish heat impregnated with the necessary amount ofmoisture.

To this end the invention consists in an improved oil-stove embodyingcertain novel features, details of construction,and arrangements ofparts, as hereinafter particularly set forth, illustrated in thedrawings, and incorporated in the claims hereto appended.

In the accompanying drawings, Figure 1 is a perspective view of theimproved stove, the same being partially broken away at top and bottomto show the interior arrangement. Fig. 2 is a vertical sectional view ofthe same. Fig. 3 is a plan View of the stove with the lid removed.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings.

The improved heating-stove contemplated in this invention comprises twodrumsan upper one and a lower one. The stove, as a whole is mounted upona suitable base 1, which may be either of cast or galvanized iron andeither annular in form or square or rectangular, as may be found mostexpedient. The base 1 has its open center covered by means of a bottomsheet 2, which is imperforate, and the upper portion of the base 1 hasbolted or otherwise secured thereto a second sheet 3, the center ofwhich is left open and flanged, as indicated at 4, to receive anoil-fount 5. Adjacent to the opening in the sheet 3 the latter issupported and braced relatively to the bottom sheet 2 by means of aseries of metal straps 6, arranged at intervals around the opening andconnecting the sheets 2 and 3, as shown. The oilfount 5 is removablyfitted in this opening, and comprises a center-draft burner having anannular wick of any desired size, according to the size and capacity ofthe stove. The base 1 is mounted upon rollers or casters '7, journaledon horizontal spindles 8, mounted in spaced depending ears 9, so thatthe stove may be moved easily from place to place.

The base 1 upon its upper side is provided with an annular upwardly-projectin g rim 10, to which is bolted an annular metal sheet 11,constituting the lower drum of the stove. superposed above the lowerdrum and spaced at a distance therefrom is an upper drum 12, consistingof an annular sheet 13, the bottom edge of which is joined to ahorizontal sheet 14, forming the bottom of the upper drum, and thelatter is supported upon the lower drum and held at a distance therefromby means of metal straps 15, substantially L- shaped and bolted,riveted, or otherwise secured to both drums. The bottom sheet 14 of theupper drum is also provided with a central opening 16, surrounded by adepending annular curb or flange 17, through which the ascending heatpasses.

Arranged within the upper drum is a radiator or deflector 18, consistingof a series of rings 19 of different diameters arranged one above theother and provided each at its bottom with a horizontal deflecting-sheet20, having'an opening 21 in its center. The several rings 19 aresupported at intervals by means of metal straps 22, bent in zigzag formand suitably secured to the outersurfaces of said rings, the lower endsof said straps resting upon the bottom sheet 14 and being securedthereto. The openings 21 in the deflectingsheets progressively diminishin size toward the top of the stove, so that as the heat passes throughthe opening 16 it impinges successively against the sheets 20 and isthereby deflected radially and horizontally, so as to distribute theheat equally to all parts of the upper drum. The burner in the base ofthe stove is supplied with a eylindrical-shapcd chimney 23, whichterminates at its upper end between the two drums, the heat from theburner passing through said chimney and upward into the upper drum,where it is de iiected in the manner above described.

In the upper portion of the upper drum is arranged an annularwater-fount 21 of segmental shape in cross-section and having an opencenter forming a shaft 25, through which the heat passes. This fount issupported at its peripheral edge above the top edge of the upper drum bymeans of L-shaped metal straps 26, as shown, and the open top of thefount 34: is closed by means of a series of covers 27, which may beeither hinged, so as to fold back, or made detachable, so that they canbe removed.

28 designates a trifurcated rest which is placed in the upper end of theshaft 25 and in the plane of the upper surface of the annularwater-fount. The end portions of the branches of the rest 28 are bentdownward at substantially right angles, as indicated at 29, and securedto the inner wall of the fount, as shown. This rest serves for a supportfor any utensil which it may be desired to place thereon for heatingwater or cooking purposes.

Above the water-fount is arranged a horizontal lid 30, which ispreferably hinged at one side to the fount or other convenient point,whereby it may be folded back for giving access to the fount and forenabling utensils to be placed upon the rest 28. A discharge-pipe 31projects from the bottom of the fount 2 1 down through the upper drumand passes out between the upper and lower drums, whereit is providedwith a faucet by means of which the water may be drawn off whenrequired.

From the foregoing description it will be seen that the heat passes fromthe burner upward into the upper drum, also carrying with it a supply ofair admitted between the upper and lower drums. The heat impingesagainst the radiating or deflecting sheets 20 and is thus distributed toall parts of the upper drum. The waterin the fount is thus heated, andas the heat escapes through the annular spaces between the top edge ofthe upper drum and the annular water-fount it is impregnated withmoisture. By throwing back the lid 30 the stove may be used for heatingwater in a suitable vessel placed upon the rest 28 or for variouscooking purposes.

The stove is extremely simple in construction and may be manufactured atlow cost, and eifects a thorough radiation of the heat. At the same timethe heat of the stove emits neither gas nor smoke and is absolutelyodorless.

It will be apparent that the shape of the drums may be altered and thatthey may be made in any desired size, and also that the stove as anentirety is susceptible of many changes in the form, proportion, andminor details of construction, which may accordingly be resorted towithout departing from the spirit or sacrificing any of the advantagesof the construction.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, 1's
